Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Upper Cheek Plates
Protects the upper frame sidewalls and limits direct material erosion of the frame.
Upper Cheek Plates (Upper Cheek Plate)— Jaw Crushers Wear part, position 03.
Location and Function
| Material Options | High-manganese steel or 400–500 grade quenched and tempered wear plate, selected to the OEM drawing and impact duty |
| Typical Properties and Acceptance Criteria | Upper cheek plates withstand lateral sliding wear and feed impact. For quenched and tempered wear plate, balance hardness with low-temperature and impact toughness, and control bolt-hole edge distances, counterbores, flatness and welding heat effects. For high-manganese steel, verify the solution-treated microstructure and work-hardening conditions. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
